Re: [xsl] Selecting uniquely one 'asset' in XSL

["Vasu Chakkera" <vasucv at hotmail dot com>]

i have added a root element( assets )  to ur xml elements and started 
working..
here is it
<assets>
<asset>Oil</asset>
<asset>Oil</asset>

<asset>Diamonds</asset>
<asset>Diamonds</asset>
</assets>

for this the xsl that would give u unique elements..

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output omit-xml-declaration="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="assets/asset"/>
</xsl:template>
<xsl:template match="asset">
<xsl:if test="not(. = preceding-sibling::asset)">
<xsl:value-of select="."/>.
</xsl:if>
</xsl:template>
</xsl:stylesheet>

or a BETTER Approach is

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:key name="assets" match="asset" use="text()"/>
<xsl:template match="assets">
<xsl:apply-templates select="asset[count( . | key('assets',.)[1]) =1]"/>
</xsl:template>
</xsl:stylesheet>
